  "heading": "In order to prevent and reduce the emissions of hazardous substances to air and water from base oil production processes, BAT is to use one or a combination of the techniques given below.",
  "text": "Technique\nDescription\nApplicability\n(i)\nClosed process with a solvent recovery\nProcess where the solvent, after being used during base oil manufacturing (e.g. in extraction, dewaxing units), is recovered through distillation and stripping steps.\nSee Section 1.20.7\nGenerally applicable\n(ii)\nMulti-effect extraction solvent-based process\nSolvent extraction process including several stages of evaporation (e.g. double or triple effect) for a lower loss of containment\nGenerally applicable to new units.\nThe use of a triple effect process may be restricted to non-fouling feed stocks\n(iii)\nExtraction unit processes using less hazardous substances\nDesign (new plants) or implement changes (into existing) so that the plant operates a solvent extraction process with the use of a less hazardous solvent: e.g. converting furfural or phenol extraction into the n-methylpyrrolidone (NMP) process\nGenerally applicable to new units.\nConverting existing units to another solvent-based process with different physico-chemical properties may require substantial modifications\n(iv)\nCatalytic processes based on hydrogenation\nProcesses based on conversion of undesired compounds via catalytic hydrogenation similar to hydrotreatment.\nSee Section 1.20.3 (Hydrotreatment)\nGenerally applicable to new units",
